"CVE-2026-43944"
],
"details": "### Impact\n_Arbitrary local code execution via deep links, CLI `--opts`, or crafted shortcuts. Affected users: electerm installs that accept protocol URLs or CLI options (affected versions listed in the original report). Exploit requires clicking a crafted `electerm://...` link or opening a crafted shortcut/command that launches electerm with attacker-controlled `opts`._\n\n### Patches\nFixed in version > 3.8.8\n\ncommits:\n\n- https://github.com/electerm/electerm/commit/8a6a17951e96d715f5a231532bbd8303fe208700\n- https://github.com/electerm/electerm/commit/a79e06f4a1f0ac6376c3d2411ef4690fa0377742\n- https://github.com/electerm/electerm/commit/0599e67069b00e376a2e962649aaad6096e63507\n\n### Workarounds\n- Disable or unregister electerm protocol handlers (Deep Link settings) and avoid clicking `electerm://` links.\n- Do not run electerm with untrusted `--opts` arguments or open `.lnk` / `.desktop` files from untrusted sources.\n- Restrict which users can launch electerm on shared machines and avoid leaving electerm installed in locations reachable by other users.\n- As a temporary measure, run electerm in a confined account or sandbox (non-admin user) to reduce impact.\n\n### References\n- Report / credit: https://github.com/Curly-Haired-Baboon\n- Electerm releases: https://github.com/electerm/electerm/releases",
